Teacher Felicia Taylor Intensive Math 8th 17 Focus 2: Proportional Relationships, Non-proportional relationships and Functions
Standard(s) Taught

#### Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.

Learning Targets and Learning Criteria

I can:

• define, evaluate, and compare functions
• use functions to model relationships between quantities
